This simulation captures the von Kármán vortex street behind a cylindrical body using Large Eddy Simulation (LES) in FLOW-3D. The iso-surfaces are colored by velocity magnitude, revealing the complex three-dimensional structure of the turbulent wake as vortices shed, stretch, and break down downstream. LES resolves the large-scale turbulent structures directly while modeling the effects of smaller eddies, making it well suited for flows where the detailed structure of the wake matters. The result is a rich, physically accurate picture of how turbulence develops and evolves in the wake of a bluff body.
